PROTECTED GAS-CYLINDER.

To all whom it may concern Be it known that I, JOSEPH A. STEINMETZ, acitizen of the United States, residing at Philadelphia, in the county ofPhiladelphia and State of. Pennsylvania, have invented certain new anduseful Improvements in Protected Gas-Cylinders, of which the followingis a specification.

My invention relates to improvements in portable gas cylinders andparticularly relates to metal cylinders or containers used for holdingoxygen, nitrogen and acetylene gases and the like. The object of myinvention is to provide a protected cylinder which may be transported intrucks and other conveyances, by standing the cylinders' on end,

' side by side, or in a horizontal position, one

' on top of the other, without noise due to the cylinders bumpingtogether and striking each other; a further object of my invention is toutilize the rotecting means upon the cylinders for liftlng and handlingthe cylinders, thereby dispensing with the metal handles which haveheretofore been used. My improved protected gas cylinder is particularlyadapted for the transportation of gas in time of war, when under coverof darkness or smoke screen, the battle line is stealthily advanced andsilence is a vital necessity.

Likewise in making preparation fora gas attack it is necessary to bringup the con tainers silently and unobserved.

.or more rings or loops ofresilient material,

ofthemselves non-noise producing under shock orimpact,

Referring to the drawing; Figure 1, is a perspective with my improvedprotecting device and the representation of a man'in the act of liftingv the cylinder by utilizing the protecting device as handles; Fig. 2, isa side elevation of two protected cylinders, shown standing side byside; Fig. 3,

cylinders provided with protecting devices and placed in a horizontalposition, and Fig. 4, is a side elevation of a' cylinder showing amodified form of the protecting device.-

.In the accompanying drawing in which like reference characters refer tolike parts, 1 represents the gas cylinder and 2 represents theprotecting device encircling the cylinder. The protecting device 2 maybe of any non-resonant materlal which will separate the metal cylinders.In the drawing a piece of hemp rope 2 is shown as the protecting means.This material has been found in practice to be the most effective andthe least expensive.

The coil of rope 2 loosely encircles the cylinder and the ends of therope' are spliced together as shown at 3. in the rope, due to the splice3, is an advantage as it tends to prevent the cylinder from Theenlargement rolling when in a horizontal position. The

is located adjacent to the top and the other adjacent to the bottom ofthe cylinder. The coils of rope Q'are held in place upon the cylindersby keepers 5 which are attached to the cylinders by welding or brazing.Said coils of rope 2 are thussecurely held in place upon the cylindersso that the coils may be conveniently used as handles for lifting thecylinders.

' The rope may be coiled around the cylinder, as shown-in Fig. 4, or inany similar manner, without departing from my invention.

Having thus described -my invention I claim and desire to secure byLetters Patent:

1. A high pressure metal cylinder having a high sonorous qu'ality,meansrigidlyattached to said cylinder, and a non-resonant member coiledloosely around the cylinder to form a handle and reduce the sonorousquality of the cylinder, said looseness permitting the insertion of thehand between the said member and the cylinder, the said non-resonantmember being retained in place near its ends by the said means.

2. A high pressure metal cylinder having a high sonorous quality, meansrigidly attached to said cylinder, and an endless band of non-resonantmaterial loosely encircling said cylinder and retained in place by saidband.

' means, said loosenesspermitting the inserprotect the latter and holdthe cylinder from tion of the hand between the cylinder and rolling whenin a horizontal position. 10
